Abstract: PURPOSE: A method for forming a transistor having a gate insulating layer of a high dielectric constant is provided to prevent the gate insulating layer from being damaged during etch of a gate electrode. CONSTITUTION: After an adhesion layer(3) is formed on a semiconductor substrate(1), a gate insulating layer(5) having a high dielectric constant is formed on the adhesion layer(3). Then, a barrier metal layer(7a) and a conductive layer(9a) are sequentially formed on the gate insulating layer(5). Thereafter, a mask layer(11a) such as an oxide layer or a nitride layer is formed on the conductive layer(9a) and patterned through a photoresist pattern thereon. After removing the photoresist pattern, the conductive layer(9a) is etched with a plasma gas including chlorine and oxygen by using the patterned mask layer(11a) as a mask. The barrier metal layer(7a) is then etched with a plasma gas including chlorine and oxygen by using the etched conductive layer(9a) as a mask. The gate insulating layer(5) has an excellent etch selectivity to the both etched layers(7a,9a), so that the gate insulating layer(5) is not damaged.
